4 Claims.

This invention relates to new and useful improvements in a double slidewindow.

The invention has for an object the construction of a double slidewindow which is characterized by a vertical window frame, sash tracks onthe top side and the bottom arm of the frame, and sashes arranged onthese tracks in a particular manner.

A further object of this invention is to arrange the top portion of thesashes to work in grooves in the top arm of the frame, and to provideelements on the sashes for engaging the frame to hold the sashes on thetracks, and movable to positions which permit said sashes to be movedfurther into the grooves when desired so that they are removable fromthe tracks.

Still further the invention proposes to arrange the sashes in adjacentpairs, the elements of each pair capable of sliding past each other, orto be extended across the window frame.

Another one of the objects of this invention is to arrange the sasheswithin the window frame in two pairs, namely a front pair, and a rearpair.

The invention also contemplates the provision of a transom arranged inthe: top of the window frame and having transom door elements eachadapted to pivot to an open position in the same direction.

Another one of the objects of this invention resides in the provision ofa means for holding the sash elements of each pair of sashes in an openposition.

Still further the invention contemplates an arrangement which will drawthe sash elements of each pair of sashes together laterally Whileforcing them apart endwise so as to firmly lock them within thewindowframe.

For further comprehension of the invention, and of the objects andadvantages thereof, reference will be had to the following descriptionand accompanying drawings, and to the appended claims in which thevarious novel features of the invention are more particularly set forth.

In the accompanying drawings, forming a material part of thisdisclosure:-

Fig. 12 is a sectional view taken on the line l2l2 of Fig. 11.

The double slide window, according to this invention, comprises a.Window frame ii! having a bottom arm m a top arm N and side'arms lfiSash tracks H are mounted upon the top side of the bottom arm Hi Windowsashes I2 are slidably mounted on these tracks H and in grooves 53formed in the top arm 3'. These sashes are arranged in pairs. There is afront pair Hi 13, and a rear pair [3 [3 Each pair of sashes has sashelements which are adapted to be moved to a position in which they aresuperimposed on each other when viewed in front elevation, when thewindow is open, or they may be moved to a position in which they areadjacent to each other (as shown in Fig. 1) and then the window isclosed.

An element l 5 is mounted on each sash element and is adapted to engagethe top arm l of the window frame to hold the sash on the track I I.These elements l5 are pivotally supported by pintles l6 sothat they maybe pivoted slightly downwards as shown by the full lines in Fig. 6. Thenthe window sash element is free and may be slightly lifted up furtherinto the grooves l I. When thus lifted the bottom of the sash elementmay then be swung out and disengaged from the track H.

Each element l5 comprises a body portion l5 provided with a knob l8 bywhich it may easily be gripped to be moved from one position to theother. The dotted line position in Fig. 6 illustrates the position inwhich the element l5 prevents the sash element from being disengagedfrom the track H.

The adjacent edges of the sash elements of each pair of sashes, when thesashes are closed, have Weather strips 20' mounted thereon andcooperative with each other. These weather strips are of channel shapein transverse cross sections as may be seen from an inspection of Fig.5. When the sash elements of a pair of sashes are in the closed positionthe arms of these weather strips engage each other and form a weathertight joint. These weather strips extend from a point 20' slightly belowthe element I5 downwards completely to the bottom of the sash element.

A means is provided for holding the sash elements of each pair of sashesclosed. This means consists of a bar 23 which is pivotally mounted by apintle 24 upon an inner edge of one of the sash elements. This pintle 24is mounted on a bracket 25 secured to the sash element. This bracket 25has a projecting pin 26 which limits pivoting of the bar 23 to thevertical and from the vertical in one direction. A knob 2'! is attachedto the bar 23 by which the bar may be moved. In the vertical position ofthe bar 23 the holding means is inoperative and the sash elements may bemoved to an open position. When the bar 23 is pivoted to a position asshown in Figs. 6 and 8 it will engage into a groove 23 formed in theadjacent sash element and so hold the sash elements against relativemotion. 7

The frame ID has a top extended portion I0 which is formed by the arm I0a top arm 10 and the side arms IO This extended portion forms a framefor a transom. There are transom elements 30" and 30 hingedly mounted atspaced positions withinsaid frame. The transom element 30 issubstantially above the front pair of sashes and the rear transomelement 30 is substantially above the rear pair of sashes. The fronttransom element 30 is supported by a hinge 3| connected with a bottomedge thereof by which the transom element is hingedly supported so as tobe openable when the top edge is drawn inwards. In the closed positionthe transom element 3ll -engages a strip frame 32 mounted within thetransom frame. This transom is provided with a lock 33 cooperative witha keeper 34 mounted on the transom frame. The rear transom element 30*is supported by a hinge 35 connected with a top edge and the frame. Thistransom element 30 is'also provided with a lock 36 cooperative with akeeper element 31 on the frame by which it may be locked in the closedposition.

In Figs. 10-12 inclusive, a modification of the invention has beendisclosed Which distinguishes from the prior form merely in the meansfor holding the sash elements locked. This means comprises a bracket 39attached upon one of the sash elements and rotatively supporting atubular member 40. A stem 4! rotatively engages through the tubularmember 40. This stem hasa head 42 by which it may be turned. Upon theinner portion of the stem there is a flange 43 which prevents the stem4| from sliding out of the tubular member 40.

The inner end of the stem 4| is provided with a threaded portion 44which threadedly engages a bracket 45 upon the other sash element. Thetubular member has a cam 46 upon its inner end and projecting fingers 41on its outer end. The tubular member 40 may be turned manually bygripping the fingers 41, to pivot the cam to the position indicated bythe dot and dash lines in Fig. 11 to force the sash elements apart. Thebracket 39 is loosely mounted on the sash element so as not to interferewith the operation of the cam 46. This loose mounting is obtained bystuds 49 mountedv on the sash element and engaging through slots 50formed in the bracket 39.

The screw 44 is capable of forcing the sash elements together laterally.This lateral action is simultaneous with the endwise action of the cam46. The tubular member 40 is slidable in the bracket 39 and isrotatively mounted on the stem 4!. This permits the screw portion 44 tobe engaged into and removed from the bracket 45. As shown in Fig. 12 thescrew 44 is engaging the bracket and drawing the sashes togetherlaterally to compress the weather strips 20 between the sashes. Thehandles 41 may be turned to cause the cam 46 to simultaneously force thesash elements endwise apart from each other so that they tightly engageagainst the side arms III of the window frame. Thus the sashes arelocked, and the construction is weatherproof.

While I have illustrated and described the preferred embodiments of myinvention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to allchanges and modifications coming within the scope of the invention asdefined in the appended claims.
